Abstract: FIELD: medicine.SUBSTANCE: invention can be used in medicine, namely in obstetrics and fetal surgery, and can be used for intrauterine nephro-amnial shunting for correction of bilateral obstructive uropathies. Operation is performed on both kidneys of fetus. Install an intravenous catheter for continuous tocolysis during surgery. Fetal position is determined by ultrasonic examination. Under the ultrasound control and general anesthesia, the introducer is removed from the sterile package and introduced into the amniotic cavity; after that, the obturator is removed; the introducer is fixed in the working position with fingers of the free hand. Then conductor with stent is introduced into tube of introducer, at that extrusion extrudes stent into working zone, pigtail spiral is wrapped that provides its fixation in organ. Introducer is withdrawn, the stent is in the working position, the second pigtail restricts the stent movement from the outside. After surgical manipulation in the operating room, the fetus heart rate and blood flow in the umbilical artery is monitored ultrasonically. First, the stent is placed in a more injured kidney – IV degree of hydronephrosis, more pronounced thinning of the kidney parenchyma. In 2 weeks – in contralateral. Operation is followed by ultrasonic examination of the fetal condition.EFFECT: method provides reduced frequency of complications and mortality of fruits due to relief of symptoms of obstructive uropathies, prevents development of secondary wrinkled kidneys due to low invasiveness and accuracy of manipulations.1 cl, 3 ex

Abstract: FIELD: railway transport. 
     SUBSTANCE: invention relates to track facilities of railway transport and can be used to monitor the state of a continuous welded track. When monitoring the position of the axis of the railway track in the plan with a track measuring device, from the beginning of the summer season, using diagrams, the steepness of the unevenness of the rails of the continuous welded track in the plan, which is not yet dangerous for the movement of trains, is recorded. These initial diagrams are saved until the diagrams are obtained during the next passes of the track measuring device. Subsequent diagrams are superimposed on the previous ones, combining them along a linear coordinate (abscissa x) and determine the difference in the steepness of irregularities at the place of the maximum boom. Divide this difference by the elapsed time between the passes of the track measuring device and determine the rate of change in the magnitude of the steepness of the stress unevenness. Thus, a dangerous place is detected by the magnitude of the rate of change in the steepness of the stress unevenness. 
     EFFECT: invention makes it possible to detect in advance a place with excessive longitudinal compressive force and take measures to prevent derailing of the rolling stock.
